To aZZ whom it may concern:

Be it known that I, GEORGE W. SORIBNER,

dlesex, in the Province of Ontario and Dominion of Canada, have invented certain new and: useful Improvements in a Combined Reed-and-Pipe Organ; and I do declare that the following is a full, clear, and exact description of the same.

First, my invention relates to improvementsin combined flue-pipes and reed-organs in which a pitch-regulating device is used to place the flue-pipes in accord with the reeds during atmospheric changes; second, to aseries of flue-pipes of a firm and compact structure, and, third, to a series of reeds and reedcells throughout the compass of the organ, each reed and reed-cell being provided with two openings and mutes for the emission of tone. I attain these objects by the mechanisms illustrated in the accompanying draw- 1n gs.

. Similar letters refer to similar parts throughout the several views.

Figure 1 is a section of a series of combined flue-pipes A, provided with veneer V, sections S, and openings 0. Fig. 2 is a section of a series of combined flue-pipes A, provided with the veneer V, sections S, openings 0, and adjustable bar 13, carrying the covers 0. Fig. 3 is a vertical section through the center of an action from front to back, showing the position of keys K, reeds and reed-cells H, reed-pipes R, and flue-pipes A, a wall of the reed-cell being removed to show the position of the reed H and two tone openings and mutes M and N to each reed-cell.

A in Fig. 1 is a section of a series of combined flue-pipes which may alternate in the chromatic scale in two rows throughout the treble register. The partitions or walls between the pipes may be graded in thickness in the ascending scale, so as to place the smaller pipes overtheir wind and valves and opposite the keys that control them, the back of the row of pipes being integral for the convenient application of the pitch-regulating device and to provide a firm and compact structure. It is not practicable to place the horizontal grading-sections 2 (shown in Patent No. 552,148) in a series of combined flue-pipes.

The said sections being in the wall of the pipes Serial No. 693,676. (No model.)

and moving horizontally outward would be blocked by the wall of the adjoining pipe.

The openings 0 cannot be graded vertically by a movable section in the wall of the pipe. Hence the employment of the veneerVto afford ways for the sliding or adjustable sections S and to present a level surface to the adjustable covers 0.

The opening 0 raises the tone of the pipe above its normal pitch in proportion to the size of the opening. A semitone is sufficient for the purpose. The openings being of the same width horizontally, the size is accurately obtained by moving section S vertically until the tone of the pipe is a semitone above its nor mal pitch, and then securing it in place, treating all the pipes in the same way. We nowhave a margin of a semitone in pitch throughout the series of pipes that is available for changes in temperature. The openings being all of equal width horizontally and the covers 0 accurately adjusted to them on the bar 13, the office of barB in Fig. 2 is to move the series of covers 0 proportionately and simultaneously over or partly over the openings 0 as needed to place the pipes in accord with the reeds during atmosphericchanges. The openings- 0 should be partly closed by covers 0 when tuning the organ in a room of medium temperature.

M in Fig. 3 shows the mute and opening to the reed-cell and reed-pipe R adjusted to it. Mute and opening N are provided at the top of the reed-cell H. If mute N is closed and mute M opened, the reed tone will pass through the reed-pipe R, producing a smooth diapason quality of tone. and mute N opened, a bright reed tone will be heard. If mutes M and N are opened simultaneously, each tone will retain its normal strength and character and together produce a third quality of tone of double power from one reed.

W in Fig. 3 shows the position of the windchannels which conduct the wind from the wind-chest F to the flue-pipes A, which may be controlled by the usual co mbination-valves placed under the flue-pipes and reeds, which are not shown. The arrows show the courses of the wind.

I am aware that fiue-pipes provided with a compensating device have been used in reed- If mute M is closed 3. The combination of the series of combined flue-pipes with the veneer V, on the wall thereof opposite their speaking-mouths and sections S, bar B, and covers 0, substantially as described.

4. The combination in an organ containing reeds with the combined flue-pipes A, provided with openings 0, of the veneer V, and adjustable sections S, substantially as shown.
